Drilling Rig Automation Controller and Its Application Method for Pile Foundation Construction

Abstract

The invention discloses an automatic controller for a drilling rig, which includes an air compressor, a brake cylinder, a clutch cylinder, a height sensor and a drill stuck sensor. The control platform is used to control the work of each component according to various input technical parameters; the air The compressor is installed on the drilling rig to provide power for the brake cylinder and the clutch cylinder; the brake cylinder, the clutch cylinder and the height sensor work together under the control of the control platform to control the stroke of the drilling rig winch during the drilling process ; The stuck drill sensor sends a signal to the control platform when the drill rig is stuck, and the control platform controls the drill rig to stop automatically. At the same time, a method for pile foundation construction using the automatic controller of the drilling rig is disclosed. The invention enables the automatic operation of the drilling rig, saves manpower, greatly improves the work efficiency, speeds up the construction progress, and avoids the accident of dropping the drill when the drill sticking phenomenon occurs, and has good safety.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to an automatic controller of a drilling rig and a method for applying the same to bridge pile foundation construction. Background technique [0002] In bridge construction, unfavorable geological development is often encountered at the position of the bridge pile foundation, especially the strong development of karst caves and eroded fracture zones. Currently, manual operation of the percussion drilling rig is used for drilling construction, and each drilling rig is equipped with at least four Each operator works in turn, the labor intensity of the workers is high, the work efficiency is low, and the progress is slow. When encountering a karst cave, the drill bit cannot be lifted in time, and when the drill sticking phenomenon occurs, the drill drop accident is prone to occur, and the safety is poor. Contents of the invention [0003] The purpose of the present invention is to ...
